IP Address Validation with Previous Web Agent Releases

In an environment of 6.x QMR 2 or 3 Web Agents and older Agents, single sign-on may be affected if IP checking is configured.

Web Agents prior to v6.x QMR 2 and 5.x QMR 7 will not be able to resolve the requestor IP address and as a result, SMSESSION cookies created by those Web Agents may be discarded by 6.x QMR 2 or 3 Web Agents. This includes custom Agents using the SDK to generate SMSESSION cookies, Application Server Agents, and any other SiteMinder Agents in a single sign-on environment that use SMSESSION cookies.

Conversely, 6.x QMR 2 and 3 Web Agents may resolve a requestor's IP address, which then differs from the address resolved by an older Agent.
